After the fiascos with Tornado, and some other BAE and European colborative products, and the delays and wrangling in the Eurofighter programme some cynicism about Typhoon is inevitable and justified, but I'm always astonshed by the sheer ignorance displayed about the programme and the aircraft, and by the touchingly naive belief that the USAcan do no wrong when it comes to advanced aircraft programmes. The 'buy American' argument is all well and good, if you've not looked in any detail at F-22, C-130J, Apache, etc.
The T1 Typhoons WILL bomb. Ensuring that they will be given that capability at Block 5 (and then retrofitting the remainder) has been the main cause of the T2 signature delay.
It's likely that Typhoon's A-G capabilities will eventually be greater than JSF's - except when it comes to range and it will be a more flexible, more versatile platform.
Don't ignore the fact that external carriage of all of the weapons the UK was relying on has just been canned from JSF (no ASRAAM, no Storm Shadow) and that the aircraft's A-A capabilities are as nothing compared to Typhoon's.
Developing a Typhoon with a hook and a new gear would not be rocket science, if you absolutely had to reduce to a single FJ type, but we do not. If we need carriers, the the Typhoon/JSF mix is better than relying only on JSF.
